The TEnv class reads config files, by default named .rootrc.

Three types of config files are read: global, user and local files. The global file is $ROOTSYS/etc/system<name> (or ROOTETCDIR/system<name>) the user file is $HOME/<name> and the local file is ./<name>. By setting the shell variable ROOTENV_NO_HOME=1 the reading of the $HOME/<name> resource file will be skipped. This might be useful in case the home directory resides on an auto-mounted remote file system and one wants to avoid this file system from being mounted.

The format of the .rootrc file is similar to the .Xdefaults format:

[+]<SystemName>.<RootName|ProgName>.<name>[(type)]: <value>

Where <SystemName> is either Unix, WinNT, MacOS or Vms, <RootName> the name as given in the TApplication ctor (or "RootApp" in case no explicit TApplication derived object was created), <ProgName> the current program name and <name> the resource name, with optionally a type specification. <value> can be either a string, an integer, a float/double or a boolean with the values TRUE, FALSE, ON, OFF, YES, NO, OK, NOT. Booleans will be returned as an integer 0 or 1. The options [+] allows the concatenation of values to the same resource name.

E.g.:

Unix.Rint.Root.DynamicPath: .:$(ROOTSYS)/lib:~/lib
myapp.Root.Debug:  FALSE
TH.Root.Debug: YES
*.Root.MemStat: 1

<SystemName> and <ProgName> or <RootName> may be the wildcard "*". A # in the first column starts comment line.

Note that the environment variables (like $ROOTSYS) need to be surrounded in parentheses in order to be expanded.

For the currently defined resources (and their default values) see $ROOTSYS/etc/system.rootrc.

Note that the .rootrc config files contain the config for all ROOT based applications.

To add new entries to a TEnv:

TEnv env(".myfile");
env.SetValue("myname","value");
env.SaveLevel(kEnvLocal);

All new entries will be saved in the file corresponding to the first SaveLevel() command. If Save() is used, new entries go into the local file by default.
